IMPRVEMENT IN WINDMILLS.

Specification forming part of Letters Patent No. 131,426, datedSeptember 17, 1872.

To all whom it may concern:

Be it known that I, FRANK G. CHARLES, of Galesburg, in the county ofKnox and State'of Illinois, have invented a new and `useful Improvementin Wind-Wheels; and I do declare that the following is a true andaccurate description thereof, reference being had to the accompanyingdrawing and to the letters of reference marked thereon and being a partof this specification, in which- Figure l is a verticallongitudinalseetion of the wheel and attachments. Fig. 2 is a plan ofthe operative parts. Fig. 3 is an elevation of the swivel and spider.

Like letters refer to like parts in each figure.

rlhe nature of this invention relates to an improvement in that class ofwind wheels which is employed for pumping water; and has for its objectto provide an automatic device for throwing the sails out of wind whenthetank is lled, and to so pivot the said sails to their hub that, incombination with the governin g device and a iioat, they will ease up yout of the wind when blowing hard. The invention consists in thepeculiar construction and arrangement of the several parts for the'everal purposes, as more fully hereinafter set orth. c

In the drawing, A represents the Wheelshaft, journaled in bearings in abracket, B, revolving in a tubular vertical support, C. D is the vanesecured to the opposite side of the bracket. E is the hub secured to theouterend of the 'shaft A. In the periphery of this hub are pivoted thearms F of the sails Gr, which are secured to their arms so as to have alittle more area on the side of the arm toward the vane,

so that the tendency of the wind would be to bring the sails edgewise toit. His a connecting-rod, pivoted to a crank at the rear end of theshaft A and to the piston-rod of a pump below, (not shown.) I is aspider, sleeved on the shaft behind thewheel, with an arm for each sail,to which it is connected at the front side by a link, a, pivoted at theother end to an arm, b, projecting from the front side of the sail, nearits base and behind its axis. On the back of the spider is a swivel, I',with which engages a yoke, c, to which is pivoted a forked rod, d,sliding in bearings on top of the bracket. J is a vertical standard onthe vane-arm, to which is pivoted alever, K, weighted as at L. Thislever K is forged with two arms, the vertical one, e, rising from thefulcrum, and a horizontal one, f, on a prolongation toward the wheel.The top of thearm e isV connected, by a rod, g, to the forked rod, whichis in turn connected to the spider. M is a iioat whose weight isgraduated tothe size of the wheel, and is suspended in the tank by arod, h, from the end of the arm f of the lever K, said rod passing upthrough the tubular support G. lWhen the float M is buoyed up by thewater rising in the tankV the weight L, drawing back the spider throughits con.`

nections, rotates the sails G so as to bring them edgewise to the wind,when the wheel will cease to revolve. When thewater is drawn down awayfrom the float the latter overloalances the weight L, so as to bring thefaces of the sails athwart the wind, at an an;

gle with its course.

During the prevalence of a gale, by reason of the eccentriepivoting ofthe sails, the latter are more or less rotated on their axes, brin gingthem in the plane of the course of -the wind, consequently reducing thespeed of the wheel and necessarily lifting the oat M from the water. Ifthe float be heavily weighted the higher will be the speedof the wheel,as more power must necessarily be exerted upon the sails to lift it.

What I claim as my invention, and desire to secure by Letters Patent, is

The construction and arrangement, with relation to the shaft A, bracketB, tubular support C, vane D, hub E, arms F, and sails Gr, of the spiderand swivel I I', arms b, links a, yoke c, connecting-rods d g, weightedbellcrank lever K, standard J, rod h, and iioat M, substantially as andfor the purpose set forth.
